Single Spool holder

This is a simple single spool holder that attaches to the wall with one single screw. I've been using this for a few weeks now and haven't had an issue with the spools coming off mid print. I've included three different sizes depending on the screw size you want to use… 5mm6mm7mm I printed mine in PLA with a high wall count and it's held up, PETG might be better however isn't a must.
